HERBERT H. I -IEWITT, OF BUFFALO, NEW YORK.

, CAR-TRUCK;

Application filed January 17, 1912. Serial No. 671,607.

To all whom it may concern Be it known that I, HERBERT H. HEWITT, a citizen of the United States, and'a resident of Buffalo, county of Erie, and State of New York, have invented certain new and I useful Improvements in Car Trucks, of which I do declare the following to be a full,

clear, and exact description,reference being had to the accompanyingdrawing, forming part of this specification. Y

The present invention has relation'more particularly to that type of car truck (shown in Letters Patent No. 1,009,747, granted to me November 3, 1911), in which the side frames of the truck areso connected to the transverse member or connections between the side frames that tlie'side frames may rock in vertical planes with respect to said connecting member. I

The primary object of the present invention is to more specifically adapt thebroad features of my above mentioned patent to car trucks in which the transverse connection between the side framesconsists of some sim-,

ing shown on the sectional line 11 of Fig.

2. Fig. 2 is a. view in end elevation showing the side frame and connected parts in operative position. Fig. 3 isa View in vertl- Icalsection on line 33' of Fig. 1. Fig. 4L

is a view in vertical section on line H of Fig. 5, this section beingat the meeting faces of the section of the casting that fits within the side frame. Fig. 5 is a viewin vertical section on line 5-5 of Fig.4.

In the accompanying drawings, I have shown so much only of a car truck asis necessary to an understanding of the invention.

Each of the side frames willbe alike in construction and similarly united to the transverse connecting member of the truck.

l/Vhile the present invention issusceptible of embodiment in trucks and side frames of various constructions, I have shown the side frames as formed each of a singlecast-ing A "and of a construction similar to that set Specification of Letters Patent.

the opposite ends of the side framein such manner thatthese boxes may ro ckvertically at right angles to'thefranie. To this end eachofthe journal boxes E hasa stud H,

projecting laterally and inwardly therefrom, these studs H being formed with'bearing them.- m

Each, side frame A' is cast withaic entral opening that "is bounded by an, annular flange a, and within lllllS central opening is held, as for example, by means'hereinafter described, the spring. plank extending between ,theside frames, the ends of the truck bolster and the springs that support the bolster.

In the preferred form of my present in vention, the transverse member B that extends between the side framesof the truck consists of a metal channel bar or spring. plank, each end of which sets within a car- In the'present "case, as in the above mentioned application, the ournal boxes E are shown as: pivotallyconnected to.

portions h and k that "setwithin suitable bearings formed in the'side frame to receive rier or journal frame G that is mounted-i within the" central opening of the corresponding side frame A. Preferably, each carrier G is formed of two similar sections consisting of hollow segmental castings, the upper portions of which areti uncated and the central portion of which is formed with a large opening 5, preferably rectangular,

to receive the spring plank and'bolsterends and the bolster supportingsprings. Each section. '9 of the casting G .is'formed with a flange g", these flan es 9 being adapted to overlap the circular rim a of the central opening of the side frame A when the sections 9 of thecasting are united together as by the through bolts 9 casting'to be set within the central opening of the truck frame, and if the casting G were thus madeof arsin le iece the outer flange 9 would preferably be omitted and suitable pins or keepers would be employed to hold the casting in position with respect to the. side frame.

If the casting G were made-of a single piece, one of the flanges -g would be omitted to enablethe \Vhen .each of the castings G is within the central opening of" its corresponding side frame A, the unobstructed upper part ofthe central openingof the side frame above the casting. G will be sufficient to enable the end dropped down into the space 'of the casting.

7c of the truck bolster K to be passed through the central opening of the "side frame and G, so that the flanges Z0 and k that project laterally from the ends of the bolster K will overlap the vertical walls 6 of the casting G.

I In order the spring plank or t'ransverse connecting member B 'to the castings Gr, each of the castings is preferably formed with integral vertical studs 7 adapted to enter corresponding holes formed in the ends ofthe transverse member or spring plank B.

i In assembling the truck the circular caste ings G which in my present invention form the journals on which the side frame s rotate,

will be first appliedto the side frames, as shown in the drawing, and then the side frames will be slipped onto the ends of the bolster, the openings in the'side frames at the flattened upper side ofthe circular castings beingjust large enough to admit the ends of the bolster. The channel bar or spring plank B is then placed in position with its ends in the openings 5 of the castings G, and'the studs 7 of the castings will pass up through the correspondlng holes formed in the ends of the channel bar or spring plank. The springs S will then be set in position and the bolster will be dropped down upon them; and as the bolster is then dropped down onto the springs, the

ribs or flanges 7e, 7e atthe ends of the bolster will overlap and engage with the vertical walls 6 of the castings Gr, and by this means the side frames will be kept at proper dis tance and in parallel relation to each other.

When the parts of the truck are assembled fornse, as shown in the drawing, each of the side frames A will be free to rotate with respect to the spring plank and truck bolster. The advantages incident to enabling the side frames to rotate with respect to the transverse connection between the side frames of the truck are fully set out in my Letters Patent No. 1,009,747, and need not be enumerated here.

My present invention is particularly 'desirable in thatit enables the weight of the truck to'be materially reduced and enables the broad invention of my 'hereinbefore mentioned patent to be applied in connection with the type of spring plank and bolster of tried and approved construction.

WVhile I have described the preferred em-' bodiment of my present invention, 1 wish it understood that the details of construction above set out may be varied without departing from the spirit of the invention and that features of the invention may be employed without its adoption as an entirety.

The present invention presents the first instance of a car truck comprising side frames, transverse connecting means (such to conveniently unite the ends of as a truck bolster), supports or carriers separate from the truck bolster but interlocked with the ends thereof, and rotatably united to the'side frames. By thus providing the side frames with rotatable supports or carriers separate from the transverse connecting means, the side frames may be connected by various constructions adapted to engage the rotatable supports or carriers.

Having thus described my invention what I claimv as new and desire to secure by Letters Patent, is

'1.
